Let
Vco------------------- >Volume cone
Vcy------------------ >Volume cylinder
r= 8mm
hco----------- > height of cone=18 mm
hcy------------ > height of cylinder =54-18=36 mm
then
Vco=π*r² *hco/3--------- > π*8² *18/3=π*384 mm³
Vcy=π*r² *hcy--------- > π*8² *36=π*2304 mm³
the total cubic millimeters of sand=Vco+Vcy=π*384+π*2304=π*2688
if 10π cubic millimeters --------------------- > 1 seg
π*2688--------------------------------- X
X=π*2688/10π=268.8 seg
the answer is 268.8 seg
Answer:
do brackets or pherenthisies first then do x devide wich ever comes first then if not + or - wich ever comes first
then do all that you get your awnser my plueshure helping you bye have a good day
Step-by-step explanation:
<span> A: y=2x 15 (or whatever variables you choose to represent the colony growth and time)
B: y=2(3.5) 15;
22 colonies
C: substitute 584 with y into the original equation, so:
584=2x 15
569=2x
284.5=x; therefore, after 284.5 hours</span> Hope this helps! :D
If you want area it’s 16 if you wanted perimeter it’s 20 if your asking for the number of the width it’s 8
